| GAO rong; CAI chun; LU Chun xu（Chemical Engineering School; Nanjing University of Science and Technology; Nanjing; 210094; China） |
| Abstract：An "one pot" method to synthesize triphenylphosphine was found from the reduction by zinc of triphenylphosphine sulfide,which was prepared directly from benzene by reacting it with sulfur and phosphorus trichloride with high yield,pure product and moderate conditions. |
| Key words：triphenylphosphine; synthesis; triphenylphosphine sulfide |
